| 化學(xué)專業(yè)的同學(xué)請幫忙寫成地道的英文,謝謝我寫的句子太中式了, 請幫忙寫成地道的英文,非常感謝。①這些物質(zhì)中,物質(zhì)A、B和C為同系物。他們的結(jié)構(gòu)中都含有物質(zhì)A的結(jié)構(gòu)。B比A多一個甲基,C 比A多兩個甲基。Among these compounds, A, B and C were homologues. They all contain A structure framework. There one more methyl in the structure of B than A, and two more methyl groups in the structure of C than A. ②隨著碰撞能量的增加,m/z 100的峰增加一點(diǎn),但并沒有新的峰再出現(xiàn)。當(dāng)碰撞能量達(dá)到40eV時,m/z 100的峰消失了。As the increasing of collision energy, the peak abundance at m/z 100 increased a little, and there was no more obvious new product ion anymore. When the collision energy was up to 40 eV, the peak at m/z 100 disappeared. |

這個永不者化學(xué)專業(yè)的就可以搞定: ①這些物質(zhì)中,物質(zhì)A、B和C為同系物。他們的結(jié)構(gòu)中都含有物質(zhì)A的結(jié)構(gòu)。B比A多一個甲基,C 比A多兩個甲基。 Among these compounds, A, B and C are homologues,all of which have A structure framework. Comparing with A, B has one more methyl while B has two more methyl groups in their structures, respectively. Side note: 描述結(jié)構(gòu)為什么用過去式呢?難道昨天是同系物,明天就不是了? ②隨著碰撞能量的增加,m/z 100的峰增加一點(diǎn),但并沒有新的峰再出現(xiàn)。當(dāng)碰撞能量達(dá)到40eV時,m/z 100的峰消失了。 With the increasing of collision energy, the peak abundance at m/z 100 increased slightly, with no extra peaks (or product ions). However,the peak at m/z 100 disappeared when the collision energy was increased to up to 40 eV. |
